Like Jayfuu suggested. Buy an existing product and adapt it as needed. This cordless Dremel tool goes from 5K RMP up to 30K RPM.With some modification you can get it running slower and extend the battery life.

That won't spin a half kilogram blade though. ;)

....and a half kilo blade is non-zero diameter, so what kind of torque has this to deliver !

Everything depends on the torque you need for the lots you're driving.

You could rip apart one of these. Or just use it.
